ECTION

2.1 General Precautions

• Never attempt to insert wires, pins, etc. into the vents or other holes of the equipment.
• Do not use benzene, thinner, or the like, or any abrasive powder to clean the equipment. Wipe it with
a soft cloth.

2.2 Environmental Requirements

Meeting established environmental standards maximizes the life of the system. Be sure that the site is
not:
• In direct sunlight or in hot, cold or humid places.
• In dusty areas or in areas where sulfuric gases are produced.
• In places where shocks or vibrations are frequent or strong.
• In places where water or other fluids comes in contact with the equipment.
• In areas near high-frequency machines or electric welders.
• Near computers, telexes, microwaves, air conditioners, etc.
• Near radio antennas (including shortwave)

2.4 Site Requirements

A KSU is only for wall mounting use, and it is available to mount it on the floor with External Backup
Battery.

2.5 AC Power Requirement

A dedicated 100V-120V/220V/230V/240V 50/60Hz circuit located within 2 meter of the KSU is
required. A separate dedicated AC outlet is necessary for each KSU.
